Definitions

  • the present invention relates to transmission shafts and a method for producing same.
  • the present invention relates to elongated shafts, such as transmission countershafts, and a method of producing same involving friction or inertia welding of forged segments which are optimized for weight reduction, material cost and/or required strength.
  • Heavy-duty transmissions and the shafts utilized therein are well known in the prior art, as may be seen by reference to U.S. Pats. No. 3,105,395; 4,754,665 and 4,944,197.
  • Such transmissions typically utilize countershafts machined from one-piece solid forgings and define one or more gears, typically the gears associated with the low and/or reverse ratios, integral therewith.
  • a more recent compound transmission design utilizes an increasingly elongated countershaft which extends from the forward to the rear housing walls (see U.S. Pat. No. 5,390,561).
  • the drawbacks of the prior art are minimized or overcome by the provision of a structure and manufacturing method for an elongated shaft which will result in a less expensive and lighter weight shaft as compared to the prior art transmission shaft structures and manufacturing methods.
  • an elongated shaft work piece comprising at least one hot forged segment having a cup-shaped cavity at one or both of its ends which is welded, preferably by inertia or friction welding, to a similar hot forged segment or to a bar stock segment.
  • the welded segments define a hollowed-out work piece which is then finish machined and/or heat and/or surface treated to complete production of the shaft.
  • the hot forged segment (or segments) is configured to provide optimized weight reduction and required strength of the assembled shaft. As the strength requirements for the various segments may differ, the most cost-effective material for each segment may be individually selected.
  • Fig. 1 B is a plan view of the transmission elongated countershaft of the present invention.
  • Fig. 2 is a sectional view of a first forged segment.
  • Fig. 3 is a sectional view of a second forged segment.
  • Fig. 4 is a sectional view of a third bar stock segment.
  • Fig. 5 is a sectional view of a heavy-duty vehicular transmission utilizing the elongated front or main section countershaft of the present invention.
  • Fig. 5 illustrates a compound heavy-duty vehicular transmission 110 of the type advantageously utilizing the increasingly elongated front or main section countershaft 124 of the present invention.
  • a detailed description of transmission 110 may be seen by reference to aforementioned U.S. Pat. No. 5,390,561.
  • Transmission 110 includes a main section 112 and an auxiliary section 114, both contained within housing 116.
  • Housing 116 includes a forward end wall 116A and a rearward end wall 116B, but not an intermediate wall.
  • Input shaft 118 carries input gear 120 fixed for rotation therewith and is supported by bearing 118A.
  • the mainshaft 146 carries mainshaft clutches 148 and 150 and the mainshaft splitter clutch 180 and is supported by the input shaft 118 and the output shaft 158.
  • Shift forks 152 and 154 are provided for shifting clutches 148 and 150, respectively.
  • Mainshaft 146 is independently rotatable relative to input shaft 118 and output shaft 158 and preferably is free for limited radial movements relative thereto.
  • the main section 112 includes two substantially identical main section countershaft assemblies 122 each comprising an elongated main section countershaft 124 carrying countershaft gears 130, 132, 134, 136 and 138 fixed thereto. Gear pairs 130, 134, 136 and 138 are constantly meshed with input gear 118, mainshaft gears 140 and 142 and idler 157, which is meshed with reverse mainshaft gear 144, respectively. It is noted that, in the preferred design, countershaft gears 136 and/or 138 are formed integrally on shaft 124.
  • Mainsection countershaft 124 extends rearwardly into the auxiliary section, where its rearward end 124A is supported directly or indirectly in rear housing end wall 116B.
  • the auxiliary section 114 includes two substantially identical auxiliary countershaft assemblies 160, each including an auxiliary countershaft 162 carrying auxiliary countershaft gears 168, 170 and 172 for rotation therewith.
  • Auxiliary countershaft gear pairs 168, 170 and 172 are constantly meshed with splitter gear 174, splitter/range gear 176 and range gear178, respectively.
  • Splitter clutch 180 is fixed to mainshaft 146 for selectively clutching either gear 174 or 176 thereto, while synchronized range clutch 182 is fixed to output shaft 158 for selectively clutching either gear 176 or gear 178 thereto.
  • Auxiliary countershafts 162 are generally tubular in shape defining a through bore 162A for receipt of the rearward extensions of the main section countershafts 124.
  • Bearings or bushings 162B and 162C are provided to rotatably support auxiliary countershaft 162 on main section countershaft 124.
  • Bearing 162D directly or indirectly supports the rear ends of countershafts 124 and 162 in the rear end wall 116B.
  • the work piece 200 from which the elongated main section countershaft124 is machined, may be seen.
  • the phantom line 202 illustrates the final machined form of countershaft 124.
  • the work piece 200 is formed from a first hot forged segment 204, a second hot forged segment 206, and a third bar stock segment 208.
  • the segments 204, 206 and 208 are individually illustrated in Figs. 2, 3 and 4, respectively.
  • the first and second segments 204 and 206 are joined at weld joint 210, while the second and third segments 206 and 208 are joined at weld joint 212.
  • the welded joints preferably are done by the so-called “friction welding” or “inertia welding” process. In this process, one of the segments is caused to rotate rapidly relative to the other segment and then the segments are moved axially into sustained forced contact. This welding process, and acceptable modifications and alternatives, are well known in the art.
  • the segments 204, 206 and 208 preferably are of a typical shaft or gear grade of steel commonly used in heavy-duty transmissions such as, for example, SAE 8620H, SAE 4120RH, SAE 8627H, SAE 4130RH, SAE PS 18, SAE 4130, SAE 4817H or SAE 4817RH.
  • Segments 204 and 206 preferably are of a relatively short length relative to their diameter, allowing production by a common hot forging process, which is less expensive than a cold forging process required to forge the work piece for shaft 124 as a single forging.
  • work piece 200 and shaft 124 define two enclosed internal cavities 214 and 216, which considerably reduce the weight and material cost of shaft 124 as compared to the prior art solid structures.
  • internal cavity 214 is defined by rearwardly opening cavity 218 in the first segment 204 and forwardly opening cavity 220 in the second segment 206.
  • Internal cavity 216 is defined by rearwardly opening cavity 222 in the second segment 206 and a shallow forwardly opening cavity 224 in the third segment 208.
  • the specific shapes and locations of the cavities are selected in view of maximizing weight and material savings while retaining required shaft strength and durability and preserving ease of forging and welding.
  • First segment 204 is provided with an enlarged flanged area 226 for formation of the external gear teeth to define countershaft gear 136, while the second segment 206 is provided with an enlarged flanged area 228 for formation of the external gear teeth to define countershaft gear 138.
  • the rib 230 separating the cavities 220 and 222 in the second segment 206 is axially aligned with flanged area 228.
  • the internal and external dimensions of the various segments, and of the assembled work piece 200, are symmetrical about the axis of rotation 232 of the shaft 124.
